A 2.7 V minimum supply lets this part run from a 3.3 V rail with headroom for the cold-crank dip; the 20 V maximum covers 12 V and 24 V automotive and industrial buses without an external regulator. The 15 µV offset translates to roughly 0.15% error on a 10 mV shunt signal — good enough for a 50 A load with a 200 µΩ shunt. The 370 µA supply current is a secondary concern in most power-train designs but matters in always-on battery-monitoring nodes. ## Package and mounting — SC-70-5 footprint reality The SC-70-5 (SOT-353) package is a 5-pin surface-mount case about 2 mm × 2.1 mm. The small footprint saves board area but demands careful soldering — the thermal pad is absent, so all heat dissipates through the leads.","metaTitle":"TI INA280A3QDCKRQ1 Current Sense Amplifier, 1.1 MHz, SC-70-5","metaDescription":"Texas Instruments INA280A3QDCKRQ1 current sense amplifier: 2.7 V to 20 V supply, 15 µV offset, 370 µA supply current, -40°C to 125°C.
